The steelmaking and the automotive industries are key players in the drive to reduce greenhouse emissions and protect the environment. The development of advanced high strength steels is one of the most promising approaches for reducing vehicle weight and improving fuel efficiency. As steel producers strive to produce these new grades of steels, they are faced with challenges related to mill capability, quality and environmental control, customer needs and cost competitiveness. It is within this complex landscape that this study, undertaken jointly with ArcelorMittalDofasco, will focus on the development, processing and characterization of an Advanced High Strength Steel for underbody automotive application (chassis and wheel frame). The specifications for the final product are quite severe as they require high strength, high toughness and good formability, while being weldable. To meet these requirements, the chemistry and processing conditions of the steel need to be optimized simultaneously and taking into account the specific rolling and cooling capacity of the mill.****The goal of this project is to produce HR980 steel, which is a hot-rolled grade of steel with a tensile strength of 980 MPa. Physically-based modelling will be used to design the steel chemistry and thermomechanical processing schedule. The steels will be cast and hot-rolled at ArcelorMittal's facilities in France. The microstructure and mechanical properties of the new steel will be evaluated in order to arrive at the optimum chemistry and processing route to produce HR980 steel. The grant will train one Post-Doctoral Fellow, one Master's student and one Research Associate in an area of great importance to the Canadian economy.**

钢制和汽车行业是减少温室排放和保护环境的主要参与者。高级高强度钢的发展是减少车辆重量并提高燃油效率的最有希望的方法之一。 当钢铁生产商努力生产这些新等级的钢时，他们面临着与磨坊能力，质量和环境控制，客户需求和成本竞争力有关的挑战。 正是在这一复杂的景观中，与Arcelormittaldofasco共同进行的这项研究将重点介绍用于体内汽车底漆（机箱和车轮框架）的先进高强度钢的开发，加工和表征。最终产品的规格非常严重，因为它们需要高强度，高韧性和良好的形成性，同时可焊接。为了满足这些要求，需要同时优化钢的化学和加工条件，并考虑到工厂的特定滚动和冷却能力。****该项目的目标是生产HR980钢，这是一个钢的热卷等级，拉伸强度为980 MPa。 基于物理的建模将用于设计钢化学和热力学处理时间表。 钢将在法国的Arcelormittal设施中铸造和热卷。 将评估新钢的微观结构和机械性能，以达到最佳的化学和加工途径，以产生HR980钢。该赠款将培训一名博士后研究员，一名硕士学生和一名研究助理，对加拿大经济非常重要。**
